For realize first profiled part 11, framework 35 and sheet retainer 148 together reversible in the plane below squeezing sheet mould 274 laterally move, first profiled part 11, framework 35 and each sheet retainer 148 are positioned on the platform 50 together.As described before this paper, first profiled part 11 is shelved on the supporting construction 41, and this supporting construction 41 comprises the upper surface 47 upwardly extending a plurality of I type beams 44 from platform 50.Sheet retainer 148 is shelved on the upper surface 38 of framework 35, this framework 35 is shelved on the frame support 36, this frame support 36 is supported by the first and second screw jack actuator assemblies (53 and 56) (reversibly vertically), this first and second screw jack actuators assembly is connected in the upper surface 47 of platform 50, as describing in detail before this paper.Platform 50 is positioned in the plane of squeezing sheet mould 274 belows and can reversibly moves (for example, represented as the four-headed arrow among Fig. 1 301) along the y axle in the plane below squeezing sheet mould 274.
Platform 50 can be reversibly removable with known move mode in the plane below squeezing sheet mould 274, such as slideway, track, single wheel, in conjunction with the wheel and the combination (not shown) thereof of rail.Platform 50 can more specifically be described as and comprise top board 51 and as the upper surface 47 of the upper surface of top board 51.Top board 51 can self vertically and reversibly can be located and (for example be passed through piston, not shown), make all objects be shelved on and/or be connected in upper surface 47 (for example first profiled part 11, framework 35, sheet retainer 148, the first and second screw jack actuator assemblies 53 and 56 etc.) vertically to reorientate along the z axle together.The perpendicular positioning that can take first profiled part 11, framework 35 and sheet retainer 148 to coordinate together, reason includes but not limited to, with the clip of each sheet retainer 148 inner 157 and optionally the surface, inside 14 of first profiled part 11 be positioned to more approach or away from crowded sheet mould 274, and more specifically more approaching/away from the slit that squeezes sheet mould 274, the thermoplastic sheet 292 of heating occurs from this slit.This perpendicular positioning of top board 51 may be desirable, reason includes but not limited to, the thickness of the thermoplastic sheet 292 of control heating when the thermoplastic sheet 292 of heating is contacted with the surface, inside 14 of inner 157 and first profiled part 11 of clip, and extrude/reach this contact before the constriction of thermoplastic sheet 292 of heating, as what this paper was further gone through.
In the method for the invention, initial, first profiled part 11 and framework 35 (and sheet retainer 148) are relative to each other located, and make the upper surface 38 of framework 35 be positioned at 17 tops, circumference limit of first profiled part.For example referring to Fig. 1 and Fig. 2.When first profiled part is first to protrude profiled part when (as shown in the diagram depicted), except being positioned at top, circumference limit, the original position of the upper surface of framework can be: (i) first protrude profiled part the inside molded surface on above the terminal point; Or (ii) above the circumference limit and first protrude profiled part the inside molded surface on below the terminal point.As describing in the accompanying drawing, the upper surface 38 of framework 35 is positioned at the last terminal point top of 17 tops, circumference limit and inner molded surface 14 at first.Under the situation of the first recessed profiled part (being recessed in below, circumference limit in fact), the original position of framework makes its upper surface above the inside molded surface of the circumference limit and the first recessed profiled part.
The relative positioning of the framework 35 and first profiled part 11 can be realized according to the explanation that provides before this paper.For example, the first and second screw jack actuator assemblies (53,56) can (for example by motor 106 and each axle and transmission gear case) start, so that along mobile vertically upward frame support 36 of z axle and framework 35 (reaching correspondingly sheet retainer 148), make the upper surface 38 of framework 35 be positioned at the last terminal point top on the surface, inside 14 of the circumference limit 17 and first profiled part 11, as describing in the accompanying drawing.
In the method for the invention, the clip element 154 of each sheet retainer 148 is adjusted to open position.Each clip element 154 is positioned at open position, so that provide particularly from the passage of each sheet retainer 148 top near each clip inside 157.For example referring to the clip element 154 of visible each sheet retainer 148A-148C among the clip element 154 of the sheet retainer 148C of Fig. 8 and Fig. 3, all these is shown in an open position.In one embodiment, arm 243 withdrawals (for example in cylinder 240) of second linear actuators 222, this is used for clip element 154 is pulled back rotatably around hinge components 185, thereby clip element 154 is positioned at open position.
In the method for the invention, the thermoplastic sheet (for example 292) with heating of first surface (for example 295) and second surface (for example 298) is formed by at least one thermoplastic synthetic.Particularly, when: (i) be contacted with and remain in the clip inside of each sheet retainer; And when (ii) contacting and being pulled to intimate profile and being contacted with the inside molded surface of first profiled part, the thermoplastic sheet of heating has the temperature (for example temperature of thermoformable) that allows its thermoformable.Although the temperature of thermoplastic sheet of heating may be equal to or greater than the fusing point of thermoplastic sheet, the temperature of the thermoplastic sheet that heats more typically is equal to or greater than the softening point (or glass transition temperature) of thermoplastic sheet, and less than the fusing point of thermoplastic sheet.
In the embodiment of method of the present invention, the thermoplastic sheet of heating has the inside between first and second surfaces of the thermoplastic sheet of heating.In this embodiment, the temperature of the thermoplastic sheet of heating comes down to consistent (for example change and be less than or equal to 2 ℃ or 1 ℃) on its first surface, inside and second surface thereof.Particularly, when: (i) first of the second surface of Jia Re thermoplastic sheet is contacted with the clip inside of at least one sheet retainer, and when (ii) the second portion of the second surface of the thermoplastic sheet of the described heating inside molded surface that pasting first profiled part stretched, temperature was consistent.
The temperature of thermoplastic sheet of heating can be determined by technical generally acknowledged method, such as first and second surfaces with the thermoplastic sheet of thermocouple contact heating, and thermocouple is inserted into the inside of the thermoplastic sheet of heating.Alternatively, or in addition additionally, remote temperature sensor can be used for determining the temperature on first and second surfaces of the thermoplastic sheet of heating such as infrared sensor.
As this and employed in the claims, term " sheet " and similar term comprise term " film " and similar term such as " squeeze sheet mould " with " thermoplastic sheet of heating ", such as " crowded film mould " and " thermoplastic film of heating ".When squeezing the sheet mould and more specifically come out from the slit that squeezes the sheet mould, the thermoplastic sheet of heating typically has the thickness from 0.5mm to 25mm, more typically from 1.5mm to 15mm, and further typically from 6mm to 12mm.In embodiments of the present invention, when squeezing the sheet mould and come out, the thermoplastic sheet of heating has the thickness of 9mm.At the thermoplastic sheet that extends heating and be taken in the process that contact with the inside molded surface outline of first profiled part, the thickness of the thermoplastic sheet of heating (thermoplastic sheet of the heating when coming out from crowded sheet mould slit) typically reduces.The thermoplastic sheet of the shaping of the moldings of being made by method of the present invention typically has the thickness from 0.25mm to 12.5mm, more typically from 0.75mm to 8mm, and further typically from 3mm to 6mm.In embodiments of the present invention, the thermoplastic sheet of the shaping of the moldings of being made by method of the present invention has the average thickness of 4.5mm.
The thermoplastic sheet of the heating that forms in the process of method of the present invention can have any suitable width and length.Because the thermoplastic sheet of heating typically forms by squeezing the sheet mould, thus its width typically depend on and be subject to the width that squeezes the sheet mould, and more specifically squeeze the width of sheet slit of the elongation of sheet mould.The thermoplastic sheet of heating for example can have from 2.5cm to 5m or the width of 31cm to 3m or 61cm to 2m.The thermoplastic sheet of heating can have any suitable length, because it is typically formed continuously by method of the present invention.For example, the thermoplastic sheet of heating can have from 31cm to 10m or 61cm to the length of 2m.In the specific embodiment of the present invention, the thermoplastic sheet of heating has the length of width and the 5m (about 16.5 feet) of 3m (about 10 feet).
The thermoplastic sheet of heating can be formed by known method, comprises thermoplastic synthetic is melted so that form the thermoplastic synthetic of fusing, and the thermoplastic synthetic from fusing forms the thermoplastic sheet that heats then.In one embodiment also as described before this paper, thermoplastic synthetic is fusing in extruder 271 (for example single screw rod or in the same way or counter rotating twin screW extruder), this extruder have be provided with the supply side 277 of supplying with port 280 and eventually (or extruding) holds 283.The terminal 283 of extruder and crowded sheet mould 274 (for example by conduit 289) fluid communication.The thermoplastic synthetic of fusing forms in extruder, and (by conduit 289) forward and by squeezing sheet mould 274, so that form the thermoplastic sheet (for example 292) of heating.The thermoplastic sheet of the heating typically slit from squeeze the sheet mould comes out, and from it vertically and whereabouts, gravity ground.Squeezing the sheet mould can select and operation according to the explanation that is provided before this paper.
The thermoplastic sheet 292 of heating comes out from squeezing sheet mould 274, makes the inside molded surface 14 of its second surface 298 towards inner 157 and first profiled part 11 of clip of (for example in the face of) sheet retainer 148.The first surface 295 of the thermoplastic sheet 292 of heating is the clip inner 157 and the inner molded surface 14 of (for example upwards away from) sheet retainer 148 dorsad.
The thermoplastic sheet 292 of the second surface 298 of the thermoplastic sheet 292 of heating and heating self be described as about the present invention have first, second portion and third part.For the purpose of setting forth, and with reference to Figure 12, the first 304 of the second surface 298 of the thermoplastic sheet 292 of heating be positioned at generally near or towards the position on the whole limit 307 of sheet 292.The second portion 310 of second surface 298 is positioned at the position of central area of the thermoplastic sheet 292 of heating generally.The position in the zone that the third part 313 of second surface 298 (for example gets involved between the two) between the first 304 and second portion 310 of the thermoplastic sheet 292 that heats generally.First surface 295 also can similarly be described as and has first 304, second portion 310 and third part 313, and they are at the opposite side (promptly on first surface 295) with respect to the second surface 298 of the thermoplastic sheet 292 of heating.In addition, the thermoplastic sheet 292 of heating can more generally be described as has first 304, second portion 310 and third part 313, corresponding to those parts depicted in figure 12.
In the method for the invention, the first of the second surface 298 of the thermoplastic sheet of heating (for example 304) is contacted with the clip inside 157 of the clip portion 151 of at least one sheet retainer 148.Typically, when the thermoplastic sheet 292 of heating formed, it sequentially was contacted with the clip inside 157 of the sheet retainer 148 of arranged in succession.For example, when the thermoplastic sheet 292 of heating when squeezing sheet mould 274 and come out and extending downwards, framework 35, sheet retainer 148 and first profiled part 11 can be in the planes below squeezing sheet mould 274, and (for example y axle in Fig. 1) laterally moves (as described before this paper), for example the direction of arrow 302 in Fig. 3.With reference to Fig. 1 and Fig. 3, thermoplastic sheet 292 formation when heating, and the framework 35 and first profiled part 11 are when it is laterally mobile down, and the first 304 of the second surface 298 of the thermoplastic sheet 292 of heating is incorporated into by adjoining land and contacts so that the clip of following tactic retainer 148 is inner: sheet retainer 148G; Sheet retainer 148C and 148F; Sheet retainer 148B and 148E then; Sheet retainer 148A and 148D; And final sheet retainer 148H.
In the method for the invention, clip element 154 then moves on to closing position, so that clamp and keep being received in the first of the thermoplastic sheet of the heating in the clip inside 157.More specifically, the part of clip element 154 is introduced in 304 one-tenth adjacency of first and the clamping/maintenance relation with the first surface 295 of the thermoplastic sheet 292 that heats, and the first 304 of the second surface 298 of sheet 292 is adjacent to the upper surface 183 of front portion 181 of the substrate 172 of sheet retainer 148 with keeping simultaneously.
After the thermoplastic sheet of heating had touched the clip inside of all sheet retainers, the clip element of all sheet retainers can as one man move to closing position.For example, the clip element 154 of sheet retainer 148A-148H can as one man move to closing position.Alternatively, be introduced in the clip that is contacted with the sheet retainer in succession when inner in the first of second surface of the thermoplastic sheet of heating, the clip element of sheet retainer can sequentially move to closing position.For example, the clip element 154 of each sheet retainer 148 is moved to closing position with following order: sheet retainer 148G; Sheet retainer 148C and 148F; Sheet retainer 148B and 148E then; Sheet retainer 148A and 148D; And final sheet retainer 148H.
In one embodiment, the arm of second linear actuators 222 243 extends the outside of cylinder 240 (for example to), and it is used for around the mobile rotatably forward clip element 154 of hinge components 185, therefore clip element 154 is positioned at closing position.For example referring to the clip element 154 of the sheet retainer 148A of Fig. 8, it is in the close position.With reference to Fig. 4, the clip element 154 of whole eight sheet retainer 148A-148H is in the close position, and wherein the first of Jia Re thermoplastic sheet 292 is clamped and remain in the clip inside 157 of each sheet retainer.In addition, in Fig. 4, the thermoplastic sheet 292 that remains on the heating in the sheet retainer of framework 35 separates with crowded sheet mould 274.Although do not describe in Fig. 4, the part of the thermoplastic sheet 292 of heating can still be come out from squeezing sheet mould 274, but separates with the thermoplastic sheet 292 that remains on the heating in the sheet retainer 248.
As described before this paper, clip inside 157 can by the inner surface 160 of clip element 154 and: (i) upper surface 38 of framework 35 is positioned at that part of under it; And/or (ii) the combination of the upper surface 183 of the front portion 181 of the substrate 172 of sheet retainer limits.In one embodiment, the first of the thermoplastic sheet of heating remains in the clip inside 157, and this clip inside 157 is limited by the combination of the upper surface 183 of the front portion 181 of the substrate 172 of the inner surface 160 of clip element 154 and sheet retainer.Correspondingly, the first of the thermoplastic sheet of heating clamped/remain between the upper surface 183 of front portion 181 of substrate 172 of at least a portion of inner surface 160 of clip element 154 and sheet retainer.
Along with the first of thermoplastic sheet of heating remains in the clip inside of sheet retainer, first profiled part 11 and framework 35 are relative to each other located, so that with the second portion of the second surface of the thermoplastic sheet 292 of heating (for example 310, Figure 12) be contacted with at least a portion of the inside molded surface 14 of first profiled part 11.For contacting of at least a portion of the second portion of the second surface of the thermoplastic sheet realizing heating and inner molded surface: (i) first profiled part 11 can vertically be reorientated (for example axially go up along z and move), and framework 35 and sheet retainer 148 are vertically fixing; (ii) first profiled part 11 is vertically fixing, and framework 35 and sheet retainer 148 can vertically be reorientated (for example axially moving down along z); Or (iii) first profiled part 11 can vertically be reorientated (for example axially go up along z and move), and while framework 35 and sheet retainer 148 can vertically be reorientated (for example axially moving down along z).
In one embodiment, and with reference to Fig. 4 and Fig. 5, first profiled part 11 comes down to fix with respect to perpendicular positioning, and framework 35 (with sheet retainer 148) is reversibly and controllably vertically orientable (for example along the z axle).In this embodiment, framework 35 (and correspondingly sheet retainer 148) is (for example along the z axle vertically downward) of location reversibly, controllably and vertically with respect to the first vertically fixing profiled part 11, thus the contacting of at least a portion of the second portion (for example 310) that causes the second surface (298) of the thermoplastic sheet 292 that heats and the inside molded surface 14 of first profiled part 11.Framework 35 can move along the z axle with sheet retainer 148, so that be positioned at 17 belows, circumference limit of first profiled part 11.According to the explanation that is provided before this paper, framework 35 can reversibly and vertically be located by the first and second screw jack actuator assemblies (53,56).
According to the original position of framework 35 with respect to inner molded surface 14, at least a portion of the second portion of the second surface of the thermoplastic sheet of heating and the inside molded surface of first profiled part contact can prior to, simultaneously in or contact (or clamp maintenance) generation of back in the clip inner 157 of the contacting of the clip inside 157 of the first of the second surface of the thermoplastic sheet of heating and the clip portion 151 of sheet retainer 148 (or clamp keep)/in the clip portion 151 of sheet retainer 148.For example, framework 35 can be located such that at first that its upper surface 38 is in the last terminal point below (under the situation of first profiled part that protrudes) of the inside molded surface 14 of 17 tops, circumference limit and first profiled part 11, in this situation, the second portion of the second surface of the thermoplastic sheet of heating contact inner molded surface a part can prior to or simultaneously in the second portion and clip inside/contacting and/or maintenance in clip inside of the sheet of heating.In embodiments of the present invention, clip inside 157/ the contacting in the clip inner 157 of the clip portion 151 of sheet retainer 148 (or clamping maintenance) of the first of the second portion of the second surface of the thermoplastic sheet of heating and the second surface that contacts the thermoplastic sheet that occurs in heating of at least a portion of the inside molded surface of first profiled part and the clip portion 151 of sheet retainer 148 afterwards.
Prior to, simultaneously in or the back in the contacting of at least a portion of the second portion of the second surface of the thermoplastic sheet of heating and the inside molded surface of first profiled part, each sheet retainer (with the first of the sheet that remains on the heating in its clip inside) laterally moves to the lateral attitude that is selected from towards the circumference limit 17 of first profiled part 11 and/or deviates from circumference limit 17 independently.For example, when framework 35 vertically moved down (and the second surface of thermoplastic sheet of heating be introduced in at least a portion of the inside molded surface of first profiled part contact), each sheet retainer 148 can be constantly and/or is laterally located with respect to the circumference limit 17 of (also promptly towards and/or deviate from) first profiled part 14 off and on.Alternatively, vertically move down and the second surface of the thermoplastic sheet that heats correspondingly is introduced in before at least a portion of the inside molded surface of first profiled part contacts at framework 35, each sheet retainer 148 can laterally be reorientated independently with respect to circumference limit 17.Further alternatively, the second surface that has vertically moved down the thermoplastic sheet of the bottom of its vertical stroke (for example) and heating at framework 35 correspondingly has been introduced in after at least a portion of the inside molded surface of first profiled part contacts, and each sheet retainer 148 can laterally be reorientated independently with respect to circumference limit 17.
In the specific embodiment of method of the present invention, laterally move at least one sheet retainer to the step of (with respect to model circumference limit) lateral attitude before following steps, in fact simultaneously and at least one execution afterwards: first profiled part and framework are relative to each other located, so that the second portion of the second surface of the thermoplastic sheet of described heating is contacted with at least a portion of the inside molded surface of first profiled part.More specifically, laterally move to a few sheet retainer to the step of its relative lateral attitude in fact simultaneously in and/or the back carry out in relatively locating the step of first profiled part and framework.Further particularly, laterally moving to few sheet retainer to step of its relative lateral attitude side by side carries out with the step of relatively locating first profiled part and framework in fact.
In embodiments of the present invention and described before as this paper, each sheet retainer can be by extending or the reversibly retractable-arm 219 of first linear actuators 192 of withdrawing laterally reorientate independently.For example, when arm 219 extended cylinder 216, sheet retainer 148 moved along the circumference limit 17 that the x axle laterally deviates from first profiled part 11.Correspondingly, when arm 219 was withdrawn in the cylinder 216, sheet retainer 148 laterally moved on the circumference limit 17 of first profiled part 11 or the direction on the circumference limit 17 of first profiled part 11 along the x axle.
The sheet retainer (with keep/be clamped in its clip inside in the first of sheet of heating) the thickness of at least a portion of the second portion that laterally moves the thermoplastic sheet that is used to control the heating that contacts with the inside molded surface of first profiled part.In addition, the sheet retainer (with keep/be clamped in its clip inside in the first of sheet of heating) the second portion of the second surface that laterally moves also auxiliary and the thermoplastic sheet of strengthening heating contact with the intimate outline of the inside molded surface of first profiled part.
Be not inclined to by any theory and limit, and based on evidence on hand, should believe, when the sheet retainer is laterally mobile towards the circumference limit of first profiled part, be contacted with inner molded surface (tube model is not to protrude or recessed pattern) along with the sheet that heats is introduced in, the sheet material of relatively large heating can be used.The thermoplastic that is present in the relatively large heating of sheet retainer on the model in the place that model moves that part of causes increasing at this regional sheet thickness (and correspondingly at the moldings that increases thickness that has in this zone).Correspondingly, to deviate from the circumference limit of first profiled part horizontal when mobile when the sheet retainer, is contacted with inner molded surface (tube model is not to protrude or recessed pattern) along with the sheet of heating is introduced in, and the sheet material of more a spot of heating can be used.The thermoplastic that is present in the more a spot of heating on model that part of that the sheet retainer deviates from the place that model moves causes reducing at this regional sheet thickness the moldings of thickness (and correspondingly reduce having of this zone).
Around the circumference limit of model, locate under the situation of a plurality of laterally repositionable retainer (for example 148A-H), because for example some sheet retainers move towards the circumference limit, and other sheet retainer deviates from the circumference limit of model and moves, thus the thickness of the sheet of heating can be in the zones of different of model/on change.
Has the complex internal molded surface at first profiled part, for example have the part that can be called protrusion and can be called under the situation of other recessed parts, some sheet retainers can be towards the circumference limit laterally move, and other sheet retainer deviates from the circumference limit and laterally moves.For example, sheet retainers of those contiguous inside molded surface parts of protruding can deviate from the circumference limit and laterally move; And the sheet retainer of the inside molded surface part of those adjacent recessed can laterally move towards the circumference limit; Or vice versa.Alternatively, or in addition additionally, when the second surface of thermoplastic sheet of heating is introduced in when contacting with the surface, inside of model, the lateral attitude of one or more retainers (for example can be adjusted, sequence is adjusted and/or is adjusted continuously), these positions are selected from towards model circumference limit, deviate from model circumference limit and any combination, order or its additional combination (for example, towards, deviate from and towards or deviate from, towards with deviate from).
As previously discussed, in the method for the invention, each sheet retainer can laterally be reorientated, so that influence is to the control of the thickness of the thermoplastic sheet of the heating on the each several part of the inside molded surface of first profiled part.In one embodiment, each sheet retainer can (for example towards or deviate from model circumference limit) move through one section lateral separation, this distance is typically from 2.54cm to 91.44cm, more typically from 5.08cm to 60.96cm, and further typically from 7.62cm to 30.48cm.In one embodiment, each sheet retainer can (for example towards or deviate from model circumference limit) moves through one section lateral separation of about 19.05cm.
Along with at least a portion of second portion of the second surface of the thermoplastic sheet of heating is contacted with at least a portion of the inside molded surface of first profiled part, a plurality of perforation of decompression by inner molded surface (for example 26) (for example relying on first vacuum plant 29 and conduit 32) are pumped into.The second portion of the second surface of the thermoplastic sheet of heating (because decompression) is drawn into the close profile that is contacted with and is matched with inner molded surface of close relative.For example referring to Fig. 6.
The inside molded surface of first profiled part can optionally be heated, so that the second portion of the second surface of the thermoplastic sheet of auxiliary heating and the inside molded surface of contoured are complementary.Yet, owing to the waste heat in the thermoplastic sheet that is retained in heating (, for example using), so typically do not need to heat separately the inside molded surface of first profiled part in the method for the invention once going out to squeeze the sheet mould because it is once formation.In addition, in view of the waste heat in the thermoplastic sheet that is retained in heating, typically do not need in the method for the invention to the heating thermoplastic sheet independent or external heated.
When maintenance contacted with the intimate outline of inner molded surface, the thermoplastic sheet of heating was cooled.The cooling of thermoplastic sheet of heating causes keeping the formation of thermoplastic sheet of shaping of profile of the inside molded surface of first profiled part.The thermoplastic sheet of heating typically is cooled to the temperature less than the softening point or the glass transition temperature of thermoplastic sheet.When being cooled in its softening point or the temperature below the glass transition temperature, thermoplastic sheet is thermoformable no longer, and therefore keeps the contour shape of inner molded surface.
The cooling of the thermoplastic sheet of heating can be reached by known methods.For example, cold air can be by the first surface of thermoplastic sheet of heating, and/or the inside molded surface of first profiled part can (for example rely on conduit-unshowned freezing fluid or the refrigerant by the molded surface below, inside that is positioned at first profiled part) and is cooled.
After thermoplastic sheet fully cooled off, the thermoplastic sheet of resulting shaping (or moldings) removed from first profiled part.The thermoplastic sheet that removes shaping from first profiled part can be reached by technical generally acknowledged method.For example, one or more ejector sleeve cores (ejector core) (not shown) molded surface internally reversibly stretches out, and the thermoplastic sheet that promote to be shaped effectively leaves and away from first profiled part.Alternatively, or in addition additionally, gas (for example air) can be under pressure by a plurality of perforation in the inner molded surface (for example 26), leave and away from first profiled part thereby the thermoplastic sheet that is shaped lifted.
(for example 17) extends into the clip inside 157 of the clip portion 151 of sheet retainer 148 from the circumference limit of first profiled part 11 for the method according to this invention, the redundance of thermoplastic sheet.The thermoplastic sheet (or moldings) that this redundance of thermoplastic sheet can be used for assist formation removes from the inner surface of first profiled part.In embodiments of the present invention and with reference to Fig. 6, after thermoplastic sheet has cooled off and has hardened, and the redundance of thermoplastic sheet is in the clip inside 157 of clip portion 151 of (for example remaining on) sheet retainer 148, frame support 36 and framework 35 vertically move up, and this thermoplastic sheet (292) that causes being shaped is picked up and is left and remove from the surface, inside 14 of first profiled part 11.Because the redundance of thermoplastic sheet is in the clip portion of sheet retainer, framework 35 any suitable distance that can vertically move up, so that the thermoplastic sheet that realize to be shaped is from the separation of first profiled part, move total vertical range (the total vertical range of for example being described between Fig. 1 and Fig. 6 that moves) of 5%, 10%, 25%, 50%, 75% or 100% such as method middle frame 35 of the present invention.
Sucked by decompression and with after the intimate outline of inside molded surface of first profiled part contact at the thermoplastic sheet of heating, the redundance that extends to the thermoplastic sheet in the clip inner 157 of clip portion 151 of sheet retainer 148 from the circumference limit of first profiled part is typically put at certain and is separated along the circumference limit.Unnecessary thermoplastic sheet material can separate before or after the thermoplastic sheet that is shaped removes from first profiled part.Typically, unnecessary thermoplastic sheet material separates after first profiled part removes at the thermoplastic sheet that is shaped.
Unnecessary thermoplastic sheet material can optionally separate after first profiled part removes at the thermoplastic sheet that is shaped.Unnecessary thermoplastic sheet material can be used, for example, in such as sand milling, label, punch, insert connect and/or the moulding of japanning etc. after fixing and thermoplastic sheet material (moldings) that transmission is shaped in the operating process.After operation was finished after moulding, unnecessary thermoplastic sheet material can separate from the thermoplastic sheet material that is shaped then.
When the thermoplastic sheet of heating from squeezing the sheet mould vertically and during whereabouts, gravity ground, it may meet with constriction, this width that will cause the thermoplastic sheet of heating reduces.In order to set forth and with reference to Figure 13, the thermoplastic sheet 292 of heating is described as the displaying necking phenomenon.When the thermoplastic sheet 292 of heating falls by vertical range 316, formed constriction forward part 319 with initial width 322.Thermoplastic sheet 292 in heating further falls by after the vertical range 325, and necking phenomenon takes place, and has formed the transition portion 328 with the width that reduces changeably.After falling by distance 325, necking phenomenon is finished, and has formed the neck down portions 331 with regime width 334.The width 334 of neck down portions 331 is less than the width 322 of the initial part 319 of the thermoplastic sheet 292 of heating.
The phenomenon of sheet constriction may have many reasons, includes but not limited to: the thermoplastic synthetic of fusing, squeeze the structure (for example shape of its slit) of sheet mould, the temperature of the thermoplastic sheet of heating and their combination when the thermoplastic sheet of heating comes out from squeezing the sheet mould.The phenomenon of constriction is undesired typically because the minimizing of the width of the thermoplastic sheet of resulting heating usually wideer, the heavier and more expensive crowded sheet mould of use necessitate.
In embodiments of the present invention, the clip of the first of the second surface of the thermoplastic sheet of heating and the clip portion 151 of sheet retainer 148 inner 157 step that contact (reach and optionally sheet is clamped/remain on clip inside) occurs in before the constriction of thermoplastic sheet of heating.The thermoplastic sheet of heating is contacted with the clip of sheet retainer is inner, and (and optionally further clamping the sheet that heats therein) stoped the constriction of the thermoplastic sheet of heating in fact.With further reference to Figure 13, for example, when the first of second surface 298 vertical range 316 in (also promptly before the constriction generation) of the thermoplastic sheet 292 of heating is contacted with and optionally clamped/remains in the clip inside of sheet retainer, the constriction of the thermoplastic sheet of heating is prevented from fact, and the thermoplastic sheet of heating keeps its initial (non-constriction) width 322.
As before about the discussion of sheet former, in the embodiment of method of the present invention, first profiled part, framework and correspondingly the sheet retainer be positioned together and can in the plane below squeezing the sheet mould plane of x axle among Fig. 1 and y axis limit (for example by), move, and crowded sheet mould comes down to fix.First profiled part 11 and framework 35 (and on sheet retainer 148) can be positioned on the platform 50 together, and according to the explanation that provides before this paper, this platform 50 can move in the plane below squeezing sheet mould 274.First former 11 is positioned on the model support frame 41, and this model support frame 41 is shelved on the upper surface 47 of platform 50, and framework 35 is by the first and second screw jack actuator assemblies (53, the 56) support of the upper surface 47 that is connected to platform 50.
